NONSLIPPNG HORSESE-IOE.

Original application filed February 16, 1926, Serial No. 88,668. l Divided and this application filed January 23, 1923. Serial No. 248,848.k

This invention relates to horseshoes of the anti-slip type, and is a division oi my application Serial No. 88,668, tiled February 16, 1926.

The object of the present invention is to provide a. horseshoe having cne'or a plurality of resilient callrs adapted to grip the ground and so to prevent the animal trom slipping.

Another object ot the invention is to provide a horseshoe having callrs constructed to absorb the shock of impact ot the animals tootfall, increasing the comtort oit the horse and thereby promoting his eihciency, as well as preventing lameness.

In the drawing, one adaptation of the invention is disclosed:

Fig. 1 is a bottom plan of the end oit a horseshoe having a longitudinally slidable calli;

Fig. 2 is a section taken along the line 2-2 of Fig. 1;

Fig. 3 is a top plan view of the'end of the horseshoe, the cover of the callz-chainber being in open position; and

Fig. l is a cross-section line eli-4t of Figs. 2 and 3.

Referring now in detail to the several tigures, each end or" the horseshoe is cut out, 'forming a chamber or recess 26 with spaced bars 25 at the opposite sides thereof and an integral end wall 27. l

taken along the rlhis recess is cinarged on the lower face of the horseshoe to 'form' a guideway for the sliding member 12- which is provided with ground engaging ianges 22. The sliding member 12 is retained and guided by extensions 20 oiC the bars 25. rlhe opposite side of the recess 26 is also enlarged forming shoulders 16 on the upper sides of the bars 25, said enlarged portion of the recess 'functioning as the guide tor the enlarged head 15 ot a bolt 111 which is threaded into a suitable socket in the sliding member 12. T he head of the bolt abats against the shoulders 16, preventing the sliding member from dropping downward, and sai-d head is provided with a korf by means ot which the bolt 14 may be screwed into the sliding member 12 sufficiently to produce a light trictional contact between said member and the lower yface of the recess in which it slides.

The chamber 26 is closed on the upper side ot' the horseshoe by a cover plate 18 which slides lin suitable guideways being held in place by suitable means, not shown, and approac-hesyso close to the head 15 of the bolt 14 that the latter can never become sutliciently unscrewed to work out ot' the sliding member 12. fr spiral spring 17 lies within the chamber 26, between the bars25, abutting at one end against the bolt 14 and at the other end against theend wall 27 of .the horseshoe. The cover platel 18 is secured tothe horseshoe in any suitable manner. l

ln operation the spring normally holds the sliding member 12 in forward position. Vhenthe horse starts to slip forward Vthe tianges 22 dig into the slipperysurtace and hold, the forward movement of the horses 'toot with the horseshoe being yieldably checked by the compression of the spiral spring. The lateral wings 22 of the slip-per 12 may beprovided with'inc-lined surfaces, as shown in Figure 2 to increase theA grip between the horseshoe and the ground.

While 1 have in the above description disclosed what I believe to be a practical embodiment ot the invention, it isrto be under-` stood that details or construction may be varied to the extent permitted by the scope of the appended claims.

What l claim is:

1. A horseshoe having arccess in eachend extending from one side to the other, one side or the recess being larger than the other forming an intermediate shoulder in said recess, a calk slidably mounted in said recess having aY portion projecting 'from one side of the horseshoe and having'a portion engaging said shoulder for' retaining said calk, resilient means for yieldably mounting said calli, and a cover 'for the opposite side of said recess.

2. A non-skid horseshoe comprising a slipper arranged slidably within a groove in the horseshoe, a pin screwed into the slipper and provided with anenlarged head, guides for the head of the pin, a spring interposed between the pin and the bottom ot the recess, and a slidable closure for the recess.

In testimony whereof I have signed my name to this specification.
